[jboss-as7-dev] Do you need property substitutions in XSLT-augmented configs?

Currently, during XSLT transformation, <socket-binding name="management-native" interface="management" port="${jboss.management.native.port:9999}"/> becomes <socket-binding name="management-native" interface="management" port="<new-value>"/> Is it ok or do you need it to be <socket-binding name="management-native" interface="management" port="${jboss.management.native.port:<new-value>}"/> ?
